On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole "map" of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named "genes" in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.
In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA tells the cell(细胞)to build its parts. Scientists have now found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one "word" means, we can help save more people from several illnesses.
Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technology(技术)wasn't limited(限制)in use.
1.When did we first know why we look like other people in our family?
A. In 2000. B. In 1953. C. In 1961. D. In 1860.
2.What did the two scientists first discover in 1961?
A. The "map" of DNA.
B. A new illness.
C. A message of DNA.
D. The language of DNA.
3.What can we do if we understand some "words" of the language inside the body?
A. Make people get new jobs.
B. Make medicine for illnesses.
C. Make maps of human.
D. Make people less attractive.
4.What do people think about this work?
A. It can cause good or bad results.
B. It can cause only good results.
C. It can cause good results but won't work.
D. It can cause only bad results.

People usually talk about two groups of colours: warm colours and cool colours. Scientists think that there are also two groups of people: people who prefer warm colours and people who prefer cool colours.
The warm colours are red, orange and yellow. Where there are warm colours and a lot of light, people usually want to be active(活跃的). People think that red example is exciting sociable(善交际的)people, those who like to be with others like red. The cool colours are green, blue and purple. These colours, unlike warm colours, are relaxing. Where there are cool colours, people are usually quiet. People who like to spend time alone often prefer blue.
Red may be exciting but one scientist says that time seems to pass more slow in a room with warm colours than in a room with cool colours. He suggested that a warm colour such as red or orange is a good colour for a living room or a restaurant.
People who are relaxing(休闲)or eating don't want time to pass quickly. Cool colours are better for offices of factories as the people who work there want time to pass quickly. Scientists don't know why people think some colours are warm and other colours are cool.
However, almost everyone agrees that warm colours remind(使想起)people of warm days and cool colours remind them of cool days. Because in the north the sun is low during winter, the sunlight appears quite blue. Because the sun is higher during summer, the hot summer sunlight appears yellow. [email protected] com
